长螺旋钻孔管内泵压CFG桩工法的应用时间不长，与振动沉管工法相比，其混合料具有超流态、和易性及保水性要求高等特点。结合实际工程，通过室内混合料的配合比试验，研究混合料的强度、和易性以及各成分含量的关系，对CFG桩的设计和施工具有指导意义。

The pressure pumped CFG piling by continuous auger drilling is a recently developed construction method. Comparing with vibrosinking mixture, the mixture is required to be of characteristics of extra fluidity, higher workability and saturation. In engineering practice, laboratory experiment of mixture ratio and study of the relationship between strength, workability and mixing ratio of the mixture will be instructive to CFG piling design and construction.
